Hi there, I'm using Neo4j 3.4.9, and have been wondering why the reported disk space is correct (4.17GB) but the rest of the metrics don't add up. There are 2.3M nodes and 5.6M relationships. Most of the nodes are short texts (support ticket replies)...
Is there a decimal or fixed-point data type in Neo4j? I'm thinking of something like DECIMAL or NUMBER in various SQL DBs or Java's BigDecimal. If not, what are the best practices if I need to work with decimal data with Neo4j (saving, calculating, r...

If you launch Neo4j on Google Cloud, you might see VM warnings that look like this: Disk size: '200 GB' is larger than image size: '10 GB'. You might need to resize the root repartition manually if the operating system does not support automatic res...
Hello everyone, I am almost newbie to Neo4J and graph databases world, and I have some doubts about importing data into Neo4J. In my case, I have several related tables in Hive which I would like to load to Neo4J. I wonder if I should use a Spark2 ap...
Consider the following nodes with relationship [top_of]: (n1)-[top_of]->(n2)-[top_of]->(n3) (n4)-[top_of]->(n2)-[top_of]->(n5) input will be a list of nodes like [n1,n3,n5]. In output, a node x from list will be removed if there is a path from anoth...
Hi, I have imported a csv file into a neo4j database. I am now using bloom to visualise the graph but im not able to expand nodes due to "Undefined node". I have included the cypher I used to import the data below as well as a screenshot of the Grap...
Hi, I have :Person, :Question, and :Answer nodes. A person can either answer a question or skip it. If they answer the question, I'm adding a relationship (:ANSWERED) between the :Person node and the :Answer node. If they decide to skip it, I'm addin...
MATCH (n:Owner),(v:Vehicles) WHERE NOT (n)-[:OWNS]->(v) RETURN DISTINCT n.email, n.name ORDER BY n.name and MATCH (n:Owner),(v:Vehicles) WHERE (n)-[:OWNS]->(v) RETURN DISTINCT n.email, n.name ORDER BY n.name is giving me the same result...What a...
I see that the Neo4j Desktop app bundles Zulu OpenJDK 11 with it, not Oracle's Java. Neo4j Desktop runs Neo4j Enterprise. From that I would assume that there's no problem with choosing OpenJDK over Oracle's JDK for running Neo4j Enterprise in the cl...
Hello, I've been struggling for days to optimize the following request: For the context, i have a graph that contains User nodes with some properties and relationships. From python, i fetch these nodes and do some calculation with them and the result...
Sorry for this stupid question. But I couldn't get it exactly when we need it to use. I see that we can have users through dbms.security. But I don't see anywhere about login, logout process for this. When I start the graph (using graph db user and p...
Hello guys, I have a working neo4j database running on AWS EC2, followed this link, SSL works perfectly except the fact that when certbot automatically renew the certificate Neo4j still use the old certificate. So in order to solve this issue, I have...
I'm trying to perform an operation that will check to see if a relationship exists on a node and if not create one. If a relationship does exist, I want to delete the relationship and then create a new one. What I have so far is: Match (w:Well {id: "...
So I have an identification of node, let say a user id. From this user id, I want to get the subgraph of he is connected to other entities such as other users, or other institution such as bank or company. Let say I want to take the eight-degree sepa...
